I agree, though I would add a face mask, some type of rubber gloves (small and handy if you need to pick up something you would rather not). . . .
I have latex-free gloves in my first aid kit.
I plan to include a poncho in the survival kit I want to build.
I don't recall if you mentioned carrying a SAK or multi-tool but I would suggest at least one preferably both.
After I first joined this forum, I bought a Swiss Army Knife and tried it out. It was not useful for my needs. A pair of EMT sheers is able to perform almost every tool-related task. I have a multi tool as part of my car kit. In the nearly three years I've had it, I used it once.
